转桨式水轮机的转轮体内,有一个活塞。在正式装机前,要做活塞的静平衡试验。以前是把活塞套装在假轴上,然后构成简支梁状,进行卧式静平衡试验。这种试验,必须制作假轴,增加了试验费用。现介绍一种不制作假轴的卧式静平衡方法。实践证明此方法达到了转桨式机组对静平衡精密度的要 Pivot turbine wheel body, there is a piston. Before the official installation, to do the static balance test piston. In the past, the piston was set on a fake shaft, and then formed a simple beam-like, horizontal static balance test. This kind of test, must make fake axle, increased test cost. Described here is a non-fake horizontal axis static balance method. Practice has proved that this method has reached the impeller balance precision static balance to be
